IMPROVEMENT IN APPARATUS FOR PITCHING BARRELS.

Specification forming part of Letters Patent No. 106,964, dated August3U, 1870.

To all whom it may concern:

Beit known that I, LOUIS SCHULZE, otLouisville, in the county of Jeiferson and State of Kentucky, have invented new and usefulImprovements in Apparatus for Pitching Barrels; and I do hereby declarethe following to be a full and correct description of the same,sufficient to enable others skilled in the art to which my inventionappertains to fully understand and use the same, reference being had tothe accompanying drawing, which makes part of this specification, and inwhich- Figure l is a side elevation of my improved apparatus. Fig. 2 isan end elevation of part of the same 5 and Figs. 3 and et are detachedviews of parts of the same.

Like letters ofrei'erence indicate like parts in the several figures.

My invention consists in certain improvements on apparatus for pitchingbarrels, which I will proceed to describe.

A in the drawing represents a frame of suitable dimensions, supporting ametallic retort composed of two. parts, B C, the lower part, B, beingheld in the frame, and the upper part,

C, being secured to it by means of what may be called a bayonet-lock, ithaving inclined edges c fitting on similar edges b on part B, which,whenturned in one direction, lock each other, but unlock when turned in theopposite direction. The retort ends in a pipe, I), which at el forms ajoint with a short pipe, c, which may be made revolving for the purposeshereinafter specified. From the bottom of' the part B of the retortextends a tube, E, connecting the retort with a fan, F. The pipe c issurrounded by a water-jacketJ", which carries a small reservoir, g. Ashort tube, h, extends from the water-jacket j' upwardly, and is at itsupper part bent downwardly into the reservoir g. The pipe c is at itsfree end bent downwardly, and is provided with slots i and openings j,and may be revolved by means of a handle, 7., which can be removed atpleas ure, being constructed as shown in Fig. The part C of the retortis provided with a door, G, having a central opening, H, which iscovered by isin glass, suitably secured in the same. This door hasbeveled side edges fitting into similar grooves in the part C, so thatthe door may be easily removed for the purpose of illing the retort, andagain closed tightly. y

I is a table having a central opening, through which moves up and down aframe, J. This frame is operated vertically by means of a treadle, K, soas to raise or lower it.

The operation of my improved apparatus is as follows: The part C beingsecured on the part B by means of the bayonet-lock described, and thepart B being filled with-suitable fuel, the latter is ignited, and thefan put in operation to create a hot blast from thc retort to the barrelto be pitched. The opening H of the door G, being covered withisinglass, enables the operator to sec the exact force of the blast andregulate the saine. A barrel is placed on the frame J, and by means ofthe trcadle K is elevated, so that the pipe c may be passed through itsbung. A sutieient quantity of pitch is placed in the barrel previous toits being placed on the frame J.

It will be readily seen that by means of the treadle barrels ofdifferent sizes can be instantly adjusted to the pipe c.

Any device may be employed to keep the frame J in place while the barrelis being pitched, and the treadle may be so arranged, by aball-and-sockct joint, that the frame J can be revolved, if desired.

The tube c being revolved, the blast is thrown out with great forcethrough the slots 'i and openings 7' to the sides, and through the mouthetthe tube to the ends of the barrel, melting the pitch anddistributing, by this revolving motion of the tube c, evenly over theentire inside ot' the barrel. lhe blast, passing withgreat force throughtube c, heats the same, and would burn the bung-hole but for theprovision of the watcr-jacketf, which is automatically fed from thereservoir g by means of tube 7L, through which the water, expanding asthe pipe cheats it, asccnds and is again poured in the reservoir.

By means of the bayonet-lock c l the upper part, (l, of the retort isprevented from b1owing oft, and can yet be easily removed for thepurpose of cleaning and iilling the retort.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The bayonet-lock c d, for the purpose ot`v uniting` the parts B and Cof the retort, substantially as described.

2. rlhe beveled door G, with its opening H covered with isinglass,substantially as and for the purpose set forth.

3. The combination and arrangement of tube c, water-jacketj', reservoirg, and tnbe h, substantially as and for the purpose described.

4. The revolving tube e, having its bent end provided with slots fi andopenings j, and operated by handle 7.-., substantially as and for thepurpose described. 5. The combin ation an d arrangement of table I,frame J, and treadle K, for the purpose ot' adjusting the barrel to theapparatus, substantially as described.
